Whether you’re going to be part of the 48,000-person crowd at the Global Citizen Festival New York event today or plan on being part of the community watching it online, it’s going to be a big, music-filled day.

Taking place on the Great Lawn in New York City’s Central Park, the large-scale affair will feature performances from major artists, chats with activists and politicians, as well as teachings on how everyone can do their part to make the world a bit better of a place.

Fans had the chance to win one of the 24,000 pairs of tickets available by completing actions to end extreme poverty. Using the Global Citizen app, users earned entries to the ticket lotteries by participating in activities that helped bring attention to specific changes the world would like to see, like “girls education, building toilets, robust foreign aid programs and more,” according to the organization’s website.

For those who were lucky enough to nab tickets, doors will open at 2 p.m. EDT, and the show is expected to begin at 4 p.m. EDT and end at 10 p.m. EDT. Don’t worry if you’re not able to attend the festival in person because there are many ways to enjoy the event on TV or online. MSNBC will be airing it, starting with a pre-show program at 3 p.m. EDT.

There will also be a live stream of the full-day concert on NBCNews.com, the Global Citizen YouTube and Twitter pages and the event’s official website. If you’d prefer to simply listen and not watch, you can do so on Global Citizen Festival Radio on iHeartRadio, online or via the radio platform’s app.

So, who exactly will you get to see and hear during the event? Here’s who will be performing at Global Citizen Festival 2018: Janet Jackson, The Weeknd, Shawn Mendes, Cardi B, Janelle Monáe and John Legend. Deborra-lee Furness and Hugh Jackman will be the event’s hosts.

The set times and order of artist performances will not be released, which means attendees, viewers and listeners will have to tune in all day to ensure they don’t miss a single exciting or inspiring moment. If you’re watching in person, don’t worry about being there for hours without anything to eat or drink as vendors will be set up on the grounds, and there will be water stations, too.
